Vanadium-graphite based cermet

ABSTRACT

This invention relates to a vanadium and graphite based cermet, and a combination of other chemical elements of lighter atomic density. The cermet comprises of vanadium and graphite which makes up 70 percent (70%) of weight. The remaining weight comprises of the elements boron, aluminum, and silicon dioxide. Said chemicals which are in powdered form are mixed together to form the cermet.

BACKGROUND OF THE INVENTION

Cermets, an amalgam of metallic and ceramic materials have been widely utilized in various means, where resistance to corrosion, abrasion, heat, moisture, impact, and the like are required. In addition to providing these qualities, cermets are lighter in weight as opposed to metals, and like ceramics can be shaped in various forms for a variety of uses. The chemical elements, vanadium and graphite adduce the following:

Melting Atomic density point in fahrenheit Characteristics Vanadium 6.11 g/cm3 1910 degrees corrosion resistant Graphite 2.26 g/cm3 3730 degrees high thermal stability

The atomic densities, melting points, and physical characteristics provided indicates those qualities when lighter density, high temperature resistance, and thermal stability and resistance to corrosion are needed. In addition to the aforementioned chemicals which comprises seventy percent (70%) of the total weight, the remaining weight is provided by the following elements:

Atomic Melting point density in fahrenheit Characteristics Boron 2.34 g/cm3 2300 degrees hardness and toughness Aluminum 2.70 g/cm3  660 degrees reflects infrared radiation Silicon Dioxide 2.33 g/cm3 1713 degrees temperature resistance

The chemical symbols for the chemical elements are: V, for vanadium; B, for boron; Al, for aluminum; SiO2, for silicon dioxide; and C, for graphite (a form of the element carbon). It should be noted that among the uses of graphite, reflection and reduction of super-high frequencies (SHF) in the microwave range. An attribute for the reducing of radar cross sections (RCS) in stealth aircraft and other vehicles.

SUMMARY OF THE INVENTION

The objective of the present invention is to provide a cermet with high resistance to corrosion, high temperature stability, resistance to impact and moistures, increased resilience (greater hardness and toughness), the reflection of infrared radiation (heat), and the reduction and/or absorption of microwave radiation. The embodiment of said invention consists of the previously mentioned chemical elements in the particulate form and size of 325 mesh, or 44 microns (44 micrometers). The measured weight for the chemicals in percent are:

vanadium-20%, graphite-50%, boron-15%, aluminum-10%, silicon dioxide-5%.

The chemical particulates, due to their size, are in the form of a powder. The powdered chemicals are mixed together, either by hand, but preferably by machine for an optimal blending to form the cermet.

Having described the invention, what is claimed is:

-   -   1) A vanadium-graphite based cermet comprising of seventy         percent (70%) weight of vanadium and graphite, and the remaining         weight comprised of the chemical elements boron, aluminum, and         silicon dioxide.     -   2) A vanadium-graphite based cermet in which the chemical         elements are in particulate form, the size of 325 mesh, or 44         microns (44 micrometers).     -   3) A vanadium-graphite based cermet where the chemical elements,         in particulate form, are the size of 325 mesh, which due to         their size are in powdered form, are in the following amount by         weight and percentage: vanadium-20%, graphite-50%, boron-15%,         aluminum-10%, and silicon dioxide-5%.     -   4) A vanadium-graphite based cermet where the chemical elements         are in powdered form are mixed together to form the cermet.
